Initially, EasyWhite Tan was developed for use in the manufacture of automotive leather. But during the early
stages of development it became clear that its chrome-like character also made it suitable for use in a very wide range of
articles, including shoe upper, garment, upholstery and vegetable type leathers.The advantage of EasyWhite Tan leathers in retanning, dyeing and fatliquoring processes

Producing soft leather, consistently [premium content]
With a reduced availability of the traditional oils used for fatliquoring, lecithin has become an important raw material for all leathers, particularly ones that need extra softness. Lecithin, a vegetable oil, has been incorporated into fatliquors comparatively recently. It is now difficult to imagine how we could produce the required buttery feel without this product. However, lecithin fatliquors are different to normally used oils, as they need more carefully controlled emulsification.
